I claim: 
     
       1. A liquid crystal display apparatus comprising a liquid crystal display panel, a drive circuit substrate including panel drive IC groups arranged on the periphery of said liquid crystal display panel to drive said panel, and a control circuit substrate connected to said drive circuit substrate for individually driving and controlling the panel drive ICs of said drive circuit substrate, said drive circuit substrate including a first drive circuit substrate, which is at least a partial drive circuit substrate and a second drive circuit substrate as the remaining drive circuit substrate,   said second drive circuit substrate being connected to a flexible connection wiring portion which is connected to input terminals of panel drive ICs provided on said second drive circuit substrate for supplying thereto a control signal to individually drive and control the relevant panel drive ICs, one end of said flexible connection wiring portion is provided with a connector inserting means, said control circuit substrate is provided with a connector means for outputting a control signal to individually drive and control said panel drive ICs provided on said second drive circuit substrate, and said connector means and connector inserting means are constituted to establish engagement therebetween for connection purposes.   
     
     
       2. A liquid crystal display apparatus according to claim 1, wherein said second drive circuit substrate is connected to said liquid crystal display panel via a connection wiring portion which is flexible. 
     
     
       3. A liquid crystal display apparatus according to claims 1 or 2, wherein at least one of said first and second drive circuit substrates connected to said liquid display panel via said first or second flexible connection wiring portion is arranged at a position below the rear surface of said liquid crystal display panel. 
     
     
       4. A liquid crystal display apparatus according to claims 1 or 2 or 3, wherein said engagement formed between said connector means provided to said control circuit substrate and said connector inserting means formed in said second flexible connection wiring portion is located at the position below the rear surface of said liquid crystal display panel. 
     
     
       5. A liquid crystal display apparatus according to any one of claims 1 to 4, wherein said control circuit substrate connected to at least said first drive circuit substrate among said control circuit substrates is connected to said first drive circuit via a separate flexible connection wiring portion. 
     
     
       6. A liquid crystal display apparatus according to claim 5, wherein said first drive circuit substrate connected to said liquid crystal display panel via said first flexible connection wiring portion and said control circuit substrate connected to said first drive circuit substrate via said separate flexible connection wiring portion, are folded and stacked against each other and are then arranged at said position below the rear surface of said liquid crystal display panel. 
     
     
       7. A liquid crystal display apparatus according to claim 6, wherein said first drive circuit substrate and control circuit substrate are stacked against each other in the condition that said flexible connection wiring portion is bent.
